摘要:We argue that the rise of online travel agencies changed the nature of competition in the airline industryfrom competition on elapsed scheduled flight times to price competition. Using flight-level data between 1997 and 2007 and geographical Internet growth patterns, we find a positive relationship between Internet access and flight times. The magnitude of this relationship is larger in competitive markets without low-cost carriers and for flights with shortest scheduled times. We also find th...

摘要:Does online availability boost citations? Using a panel of citations to economics and business journals, we show that the enormous effects found in previous studies were an artifact of their failure to control for article quality, disappearing once fixed effects are added as controls. The absence of aggregate effects masks heterogeneity across platforms: JSTOR has a uniquely large effect, boosting citations around 10%. We examine other sources of heterogeneity, including whether JSTOR dispropo...

摘要:Short-term increasing returns to production factors are usually found in empirical studies. We argue they can be due to omitted variables, particularly the intensity of factor utilization. Thanks to original French firm-level data (1992-2008), we show how increasing returns to scale disappear when working time, capacity utilization rate, and, particularly, capital operating time are introduced in the production function.

摘要:The paper develops an asymptotically valid F-test that is robust to spatial autocorrelation in a GMM framework. The validity of the F-test is established under mild conditions that can accommodate a wide range of spatial processes. The proposed F-test is very easy to implement, as critical values are from a standard F-distribution. The F-test achieves triple robustness: it is asymptotically valid regardless of the spatial autocorrelation, the sampling region, and the limiting behavior of the s...

摘要:Standard job search theory assumes that unemployed individuals have perfect information about the effect of their search effort on the job offer arrival rate. We present an alternative model that assumes that each individual has a subjective belief about the impact of her search effort on the job arrival. These beliefs depend in part on an individual's locus of control. We estimate the impact of locus of control on job search behavior using a data set of newly unemployed individuals in Germany...

摘要:We use unique longitudinal data to document an economically and statistically significant positive correlation between the facial attractiveness of male high school graduates and their subsequent labor market earnings. There are only weak links between facial attractiveness and direct measures of cognitive skills and no link between facial attractiveness and mortality. Even after including a lengthy set of characteristics, including IQ, high school activities, proxy measures for confidence and...
